And we are talking about none other than Rishabh Sinha and Digangana Suryabvanshi, who were once at loggerheads.

Apparently, Rishabh has gotten protective of Digangana and advised how to play the game. Also, Rishabh and Digangana spent some jolly time together, even after being warned by the other contestants.

The current equation has given rise to the speculation that something is brewing between Rishabh and Digangana. In fact, housemates have nicknamed the couple as 'Degree'(DigRi), according to Tellychakkar.com.

"The housemates will even question Rishabh and Digangana about their feelings, but would get no answer. However, Digangana's smile and blushing face would reveal a lot," the entertainment portal quoted a source as saying.

Interestingly, Digangana played the role of Rishabh's sister in "Qubool Hai" show in 2013. But she was kicked out of the show because of her behaviour and ugly fight with Rishabh.

The actress had even accused Rishabh of abusing her on the sets of "Qubool Hai".

But looks like the two have buried the hatchet and have become friends in the "Bigg Boss 9" house.

"Bigg Boss 9", hosted by Salman Khan, airs on Colors TV at 10.30 pm from Monday to Friday, while the weekend special episodes telecast at 9 pm.
